2. Description of the Related Art An IC card has an integrated circuit (IC) embedded in a card base material, has a recording capacity 100 times or more that of a magnetic card, and can rewrite and erase data many times. As an information recording card that replaces the card, it is desired to be put to practical use in a wide range of applications. Such an IC card can be roughly classified into a contact type IC card and a non-contact type IC card according to the type of a data transmitting / receiving unit that exchanges information with the card. Further, the card reader / writer can be roughly classified into a contact type card reader / writer corresponding to a contact type IC card and a non-contact type card reader / writer corresponding to a non-contact type IC card.
The contact-type card reader / writer is provided with a contact-type input / output terminal, which is a structure for directly connecting to an external connection terminal of a contact-type IC card, as a data transmitting / receiving unit. Further, the non-contact type card reader / writer is provided with a non-contact type data transmitting / receiving unit that transmits / receives data to / from a non-contact type IC card in a non-contact method.

[0003]

Conventionally, the contact-type card reader / writer transmits / receives data to / from a contact-type IC card having an external connection terminal, and transmits / receives data to / from the non-contact-type IC card. It was impossible to send and receive. On the contrary, the non-contact type card reader / writer cannot send / receive data to / from the non-contact type IC card in a non-contact type, and cannot send / receive data to / from the contact type IC card. there were. The present invention has been made in view of the above circumstances, and provides a transmission / reception mode conversion IC card in a card reader / writer that enables data transmission / reception with respect to a non-contact type IC card by using the contact type card reader / writer. The purpose is to do.

[0004]

In order to achieve such an object, a transmission / reception method conversion IC card of the present invention is a card body inserted into a card reader / writer corresponding to a contact type IC card, and this card. In the state where the main body is inserted into the card reader / writer, a contact-type data transmitter / receiver connected to the input / output terminal provided in the card reader / writer and the contact-type data transmitter / receiver are connected to transmit and receive data in a contactless manner. It has a non-contact type data transmitting / receiving unit, and a control chip for controlling data transmission / reception in the non-contact type data transmitting / receiving unit and controlling data transmission / reception in the contact type data transmitting / receiving unit.

[0005]

When the transmission / reception method conversion IC card is inserted into the card reader / writer corresponding to the contact type IC card, the input / output terminals of the card reader / writer come into contact with the contact type data transmission / reception section provided in the conversion IC card, A contact state is established with the non-contact type data transmitting / receiving unit via the contact type data transmitting / receiving unit. The non-contact type data transmission / reception unit can transmit / receive data to / from the non-contact type IC card by the action of the control chip. Therefore, by inserting the conversion IC card into the contact type card reader / writer, it becomes possible to transmit and receive data to and from the non-contact type IC card. In addition, when data is transmitted to and received from the contact type IC card, a card reader / writer corresponding to the contact type is used for conversion I.
It suffices to remove the C card and insert the contact type IC card into this card reader / writer.
